ALINING AND LEVELING DEVICE.

SPECIFICATION forming part of Letters Patent No. 669,527, dated March12, 1901.

Application tiled July 1l, 1899. Serial No. 723,442. (No model.)

To all whom it may con/cern:

Beit known that I, JAMES V. HULSE, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Alining and LevelingDevices, of which the following is a specification.

This invention relates to improvements in alining and leveling devices,and particularly to a device of this nature wherein the leveling iseffected by the use of a gage provided with an obscnring medium, as setforth in my prior application, Serial No. 703,218, filed January 24,1899.

My present application relates in part to features disclosed but notspecifically claimed in such prior application and in part to furtherdevelopment or amplification of such features. Said prior applicationdisclosed the Vuse of a transparent gage with an obscuring medium on theside toward the object to be gaged.

The present application relates to a gage so constituted that theobscuring medium forms part of the solid gage-body either by thegrinding or etching of the gage-face or by forming the gage-body as awhole or in part of an obscuring medium or in any other suitable manner.The said prior application disclosed the use of a ground-glass gage andalso of other solid obscuring materials; but such form of the inventionwas not specically claimed therein.

A further feature of the present invention is the provision of means forangular or tilting adjustment of the gage in a convenient and effectivemanner, such means being particularly adapted to cases where it isdesirable to remove the adjusting devices from immediate proximity ofthe gage to avoid interference with parts of the machine.

The accompanying drawings represent a gage and supporting devicetherefor constructed according to my invention.

Figure l is an elevation; Fig. 2, a vertical section; and Figs. 3 and 4,horizontal sections, respectively, on the lines A A and B B of Fig. l.

l represents the gage-plate, supported on a frame 2 and having, ifdesired, magnifying or lenticular facets 3 and gage-facets 4, the latterof which are adapted to conform to the face of the body to be alined-forexample, the faces of the two type on a double-type bar of atypeWriting-machine, as specified in my prior application above referredto. The gageplate may be held in frame 2, bezel 5, and the frame 2 isadapted to be supported and manipulated in any desired manner-forexample, as hereinafter set forth.

My invention involves the provision of obscuring means for the gage,whereby the visibility of a body as seen through the gage from abovedepends on the closeness of said body to the lower face of the gage. Ifind that this effect can be produced by a solid obscuring means to anextent sufficient for some purposes. Thus I may make the gage-plate 1 oftransparent glass and etch or grind the facets 4 of same, or I may makethe gage of opal glass or generally of any material which is translucentbut not completely or substantially transparent-for example, tourmalineof certain varietiesor I may use for this gage-plate a solid body ofdouble refracting properties, such as Iceland spar or tourmaline. In anycase the body must be diaphanous--that is, it must allow of the passageof light-but it must also be obscuring, so as to prevent direct and fullvisibility through same. It may of course consist of either a singlebody or of several solid bodies cemented or otherwise attached together.

The device is used by bringing the object in contacting relation withits gage-face 4, and the trneness or extent of contact is shown by theclearness with which the face of object appears through the gage, Thegagebody l may be provided on either face with lines 6 to aid in aliningthe object operated upon, which may, for example, be a type, as abovespecified.

The gage is preferably supported and adjusted by means of a plurality ofbars or suspending devices 7 7 7, engaging with three parts of frame 2,as by entering sockets or depressions 8 in said frame 2, and adapted tobe adjusted at their other ends by any suitable means, as by engaging invertical grooves 9 in a supporting-spindle l0, which is screwthreaded,as shown, and carries knnrled screw-rings 1l, engaging, respectively, bylugs l2 with the several bars 7, so that by rotating the different ringsany one 0r more of IOO the bars 7 may be raised or depressed to tip thegage in any desired manner.

13 represents a screw-collar giving a firmer support to the bars 7. Thespindle 10 may be clamped to a supporting-arm 14, whereby it issupported and held or adjusted to the desired position, as described inmy application above referred to. There may be, of course, more thanthree of the supporting devices 7, each adjustable independent of theothers.

Having thus described my invention, the following is What I claim as newtherein and desire to secure by Letters Patent:

l. An alining and leveling device, comprising a solid diaphanousobscuring-gage and means for adjusting said gage in contacting relationwith the object to be gaged.

2. An alining and leveling device, comprising a solid translucentobscuring-gage and means for adjusting said gage in contacting relationwith the object to be gaged.

3. An alining and leveling device, comprising a gage formed of a soliddiaphanous obscuring-body and means for adjusting said gage incontacting relation with the object to be gaged.

4. An alining and leveling device, comprising a gage formed of a solidtranslucent obscuring-body and means for adjusting said gage incontacting relation with the object to be gaged.

5. The combination Wit-h a gage, of a plurality of supporting devicesengaging with the gage at a plurality of points, and means forindependently adjusting the position of the several supporting devicessuch means comprising a spindle, bars independently adjustable in saidspindle, and screw-rings surrounding said spindle and engaging with saidspindle and said bars to adjust the bars independently. i
